The results of the inspections will be kept with the CNMP in Appendix A-2 and retained for a period of five years. All weekly inspections will include visual inspection of each of the following:The CAFO waste dikes for cracking, inadequate vegetative cover, woody vegetative growth, evidence of overflow, leaks, seeps, erosion, slumping, animal burrowing or breakthrough, and condition of the storage structure linerThe depth of the CAFO waste in the storage structure and the available operating volume as indicated by the depth gaugeThe collection system, lift stations, mechanical and electrical systems, transfer stations, control structures, and pump stations to assure that valves, gates, and alarms are set correctly and all are properly functioning.Other necessary inspection information: FORMTEXT ?????Activity/DescriptionFrequencyVisual inspection of the CAFO waste dikes for cracking, inadequate vegetative cover, woody vegetative growth, evidence of overflow, leaks, seeps, erosion, slumping, animal burrowing or breakthrough, and condition of the storage structure liner.WeeklyThe depth of the CAFO waste in the storage structure and the available operating volume as indicated by the depth gauge.Weekly FORMTEXT Visual inspection of the collection system, lift stations, mechanical and electrical systems, transfer stations, control structures, and pump stations to assure that valves, gates, and alarms are set correctly and all are properly functioning. WeeklyStorage Structure Operation & Maintenance Program FORMTEXT <Farm Name> will initiate steps to correct any condition that is not in accordance with this Storage Structure Operation and Maintenance Program. Specific records of each item below will be kept in the Appendices as noted below.If CAFO waste rises above the maximum operational volume level, the DEQ will be notified ( FORMTEXT <Phone Number>). The emergency volume will be restored within one week and removed CAFO waste will be land applied in accordance with permit conditions. The DEQ will be notified if either of these it not achievable. Descriptions of such events will be recorded in the CNMP in Appendix A-4.At some point in time during the period of November 1 to December 31 of each year, there will be a minimum available operational volume in the CAFO waste storage structures equal to the volume of CAFO waste generated from the operation of the CAFO in a six-month or greater time period (including normal precipitation and runoff in the production area during the same time period). The date of this occurring shall be recorded in the CNMP in Appendix A-4 and reported to the Department in accordance with Part II.C.5, Compliance Dates Notification. This requires notification within 14 days of achieving this milestone.Vegetation will be maintained at a height that stabilizes earthen CAFO waste storage structures, provides for adequate visual inspection of the storage structures, and protects the integrity of the storage structure liners. The vegetation will have sufficient density to prevent erosion. Woody vegetation shall be removed promptly from waste storage structures berms and other areas where roots may penetrate or disturb waste storage facility liners or waste treatment facilities. Records will be stored in Appendix A-3.Dike damage caused by erosion, slumping, or animal burrowing will be corrected immediately and steps taken to prevent occurrences in the future. Records will be stored in Appendix A-3.The integrity of the CAFO waste storage structure liner will be protected. Liner damages will be corrected immediately and steps taken to prevent future occurrences. Records will be stored in Appendix A-3.Problems with the collection system, lift stations, mechanical and electrical systems, transfer stations, control structures, and pump stations will be corrected as soon as possible. Records of these inspections and records documenting any actions taken to correct deficiencies will be kept with the CNMP for a minimum of five years in Appendix A-3. Deficiencies not corrected within 30 days must be accompanied by an explanation of the factors causing the delayed correction.CAFO waste will be stored only in storage structures as described above, except for solid stackable manure collected in-barn, prior to transfer to storage.Other necessary O & M practices: Practice DescriptionFrequency FORMTEXT ?????
